Diagnosis

Fruit globose, subtended by a funnel-shaped spathulate bract, emergent and detachable at maturity, with a persistent whorl of numerous (about 24) short laminar appendages and ovoid bodies (nectaries?). Fruit interior with a central prominence and low radial ridges. Seeds numerous (about 30), radially disposed in a continuous girdle along the inner fruit wall. Seed shapes elliptical or obovate, 1.4–1.8 mm long, straight or slightly bent, with small-celled caps on both ends. Micropylar cap operculate, in line with chalazal cap or the latter ventrally displaced and at a variable distance from a knob-like hilar scar. Seed coat of two cell layers composed of, transversely elongated and polygonal papillose cells, with fi bres in the inner layer.
